When Jack is lost at sea during a monsoon, Nim sends an email SOS to her favourite writer, Alex Rover. Little does Nim know that Alex is actually Alexandra (Jodie Foster), a recluse who lives in San Francisco, far from the tropical locations she writes about with such verve. Despite her all-consuming fear of the outside world, Alexandra is moved by Nim's plight and she follows the girl's co-ordinates – 20 degrees south, 162 degrees west – to help the girl locate Jack.

Nim's Island is a fun and frothy girl's own adventure. Foster is hilarious, playing an agora- phobic, who almost hyper-ventilates when she runs out of antiseptic hand wash.
